A groundbreaking neuro-psychological research was conducted on epilepsy patients, whom brains' neural activity is regularly monitored, and have discovered that memories of past events are stored in the same neurons in the brain which were active during the original experience.

A couple of things incorrect in the sentence.

1. "whom" is correct. It should be "whose"
2. "have discovered.." who have discovered? No mention of the doer of discovering!

A. whom brains' neural activity is regularly monitored, and have discovered that
Incorrect.

B. whom brains' neural activity is regularly monitored, and has discovered that
Incorrect.

C. whose brains' neural activity is regularly monitored, and have discovered that
Incorrect. The text in blue is not the best way to write a GMAT SC sentence. "'s" is only to be used with concrete nouns, ie nouns that can posses things. Brain can not possess 'neural activity'. Better way would be to write it as "neural activity of the brain".

D. using data from the regular monitoring of their neural activity to establish that
Correct. "established that" is the correct way to write it.

E. using data from the regularly monitoring of their neural activity to establish
Incorrect. "establish memories of the past.." is illogical. In its current form, the sentence means that using the data from the monitoring of the neural activity has established the memories. This is not logical.

A. whom brains' neural activity is regularly monitored, and have discovered that ----- whom brains is plain wrong
B. whom brains' neural activity is regularly monitored, and has discovered that ---- Same as A.
C. whose brains' neural activity is regularly monitored, and have discovered that --- What is the subject of ‘have discovered’? Very muddled with passive and active voice combo
D. using data from the regular monitoring of their neural activity to establish that---- ‘ regular monitoring’ is the correct diction; correct choice
E. using data from the regularly monitoring of their neural activity to establish --- ‘regularly monitoring’ is incorrect

1. I don't think whom is wrong as "whom" refers to the object of the sentence and the pateints here are clearly the objects
2. The subject of the sentence is research , so "the research has discovered" not "have discovered" - A and C wrong
3. In E regulalrly monitoring is incorrect
4. In D i feel to establish that is not clearly written

Hence i Feel the answer must be B

'Whom' should be used when you can replace whom by him or her ! Don't go into the terminologies but learn to apply these rules in a simple manner.
'Whose' shows possession ! In this given sentence brains of the patients are monitored and thus usage of 'whom' is incorrect. B is thus out. Another reason why B is out is the usage of "have discovered that". No plural subject in the sentence can perform this action of 'discovering'.

D is correct as an infinitive form of a verb (to + verb) shows the intention or goal ('To' form is correct if you can substitute 'to' with 'in order to' without any loss in meaning). In this case, The researchers monitored the neural activity of the brain in order to establish that Memories and the neurone are linked. This clearly shows the intention of the research conducted and this D is correct.

I eliminated D as the statement doesn't has any reference to brain, isn't it altered intent as as per original sentence we are monitoring brain's neutral activity.
But brain is missing in option D

D. using data from the regular monitoring of their neural activity to establish that


Please let me know what am I missing here

In original sentence it is said that something has been discovered, where as the meaning of OA is that the research has been conducted to establish something. Isn't there any meaning shift?
